The G series single screw pump is a new type of pump that works according to the principle of rotary meshing displacement. The main working components are eccentric screw (rotor) and fixed liner (stator).
A separate sealed chamber, where the medium flows uniformly in the axial direction, with low internal flow velocity, low noise, constant volume, and stable pressure. Therefore, there will be no vortex or agitation, and the medium will not be damaged by its inherent structure.
Due to the use of various elastic materials for the stator, Huaxiang screw pumps have characteristics that general pump types cannot handle for the transportation of high viscosity fluids and media containing hard suspended particles or fiber media.
Its flow rate is proportional to the rotational speed.
High pressure and large flow rate, can be used under high viscosity pressure
Product Introduction
The G series single screw pump is a new type of pump that works according to the principle of rotary meshing displacement. The main working components are eccentric screw (rotor) and fixed liner (stator).
A separate sealed chamber, where the medium flows uniformly in the axial direction, with low internal flow velocity, low noise, constant volume, and stable pressure. Therefore, there will be no vortex or agitation, and the medium will not be damaged by its inherent structure.
Due to the use of various elastic materials for the stator, Huaxiang screw pumps have characteristics that general pump types cannot handle for the transportation of high viscosity fluids and media containing hard suspended particles or fiber media.
Its flow rate is proportional to the rotational speed.
Advantage
Continuous low pulsation conveying, unaffected by pressure and viscosity fluctuations.
Widely applicable, capable of conveying both flowing and non flowing materials.
The medium will not be stirred, squeezed or sheared during the pumping process.
High efficiency, the conveying capacity is proportional to the speed, and the conveying capacity can be adjusted by frequency conversion.
Most liquids can be pumped with minimal agitation and pulsation.
Easy to maintain and repair, with high-voltage transmission capability.
scope of application
Petroleum industry: heavy oil transportation, oil and gas mixed transportation, oil-water separation, and waste oil recovery systems.
Chemical and pharmaceutical industries: various pastes, emulsions, suspensions, etc.
Environmental engineering: various sewage transportation, dewatering sludge transportation, metering and dosing of coagulants and their chemical agents, etc.
Mineral engineering: production equipment for titanium dioxide, kaolin, calcium carbonate, etc.
Food industry: dairy products, fruit juice, puree, vegetable sauce, beer, etc.
Paper industry: raw material equipment, pulp making, and wastewater treatment, etc.
Material comparison
Comparison of Corrosion Resistance of Four Pump Body Materials:
According to the properties of the liquid medium you are conveying, choose different materials for the stator
Natural rubber
Excellent wear resistance. The corrosion resistance is average, and it will swell when encountering some gasoline,
Nitrile rubber
Good oil resistance, moderate corrosion resistance, strong compatibility, and can be applied to most general liquid and fluid media.
EPDM rubber
High temperature resistance, wear resistance, moderate corrosion resistance, suitable for liquid and fluid media with high temperature and wear resistance
Type single screw pump
Fluororubber
Good corrosion resistance, moderate wear resistance, suitable for acid-base chemical fluid media with general corrosiveness
silicone rubber
Strong isolation, excellent corrosion resistance, food grade hygiene grade, suitable for industries such as food, pharmaceuticals, and laboratories,
Selection of motor types
Choose different types of motors based on the viscosity of the medium and the flow rate you require
Type single screw pump
Standard motor
960 RPM constant speed motor
Motors of level 6 or 8
Non variable frequency use
gear motor
Customizable rotational speed
Fixed rotational speed
High viscosity or fluidity
Poor liquids require the use of reducers
Continuously variable speed motor
Fixed speed adjustment
Practical and low failure rate
Monitor the specific speed at any time
Variable frequency motor
Low failure rate and high torque
It can be done through a frequency converter
Adjust Hertz while adjusting speed

explain:
The above performance parameters are the test data obtained during the room temperature water test.
For different media and speeds, performance parameters will vary, with flow rate values inversely proportional to concentration and viscosity, and directly proportional to speed.
Users must choose the type of pump based on usage requirements, the condition of the conveying medium, and selection principles, or consult with Huaxiang Industry customer service to determine the type of pump.
